Nevus Spilus (lentigine +compound nevus) containing ballon cell nevus.Nice case.
There lentiginous proliferation of melanocyte in the basal layer in addition to a compound nevus which shows clear cell features.So Nevus spilus.

Symmetrical compound melanocytic proliferation with clear/balloon cell change of intradermal component.
Good maturation, no dermal mitoses and no epidermal consumption.
Agree with 'Balloon cell naevus'.

I go with balloon cell melanoma. Even though maturation can be discerned with both HE and melan-A, there are some alarming findings like mitotic activity in the deeper reaches, some nested cells persisting in the deeper reaches surrounded by diffuse cells, and some pleomorphic cells scattered throughout the lesion.

I think this is a benign Balloon Cell Nevus....

Regarding my experiences with balloon cell change, I associate it most frequently in nevi (both acquired and congenital) that have other senescent features. In this case, the senescent atypia in the balloon-cell nuclei (smudgy nuclear hyperchromasia and enlargement, large nuclear pseudoinclusions, rare multinucleation) seem more prominent in the upper dermal component, which also shows the greatest balloon cell changes.
